Immutable watermarking for authenticating and verifying AI-generated output

ABSTRACT

Embodiments are directed to immutable watermarking for authenticating and verifying artificial intelligence (AI)-generated output. An embodiment of a system includes a hardware accelerator to perform processing related to a machine learning (ML) model and one or more processors including a hash generator. In one implementation, the hash generator is to identify a global unique identifier (GUID) for the ML model, generate a digital signature for content generated by an inference stage of the ML model, the digital signature based on at least the GUID of the ML model and the content generated by the ML model, and transmit the content and the digital signature to a content consumer platform.

TECHNICAL FIELD

Embodiments described herein generally relate to the field of electronic devices and, more particularly, to immutable watermarking for authenticating and verifying AI-generated output.

BACKGROUND

AI (Artificial Intelligence) and ML (Machine Learning) training and inferencing are vulnerable to multiple different adversarial machine learning threats. These threats include attacks to model extraction or reverse engineering the model, poisoning of a model during training, inversion attack to extract training data, and evasion attack in which the attacker modifies the input to evade detection.

Adversarial ML attacks are possible during both training and inferencing. As AI and ML processing continue to move into new technical fields, conventional reliance on algorithmic methods to detect and thwart adversarial attacks is insufficient, and thus additional security measures may be implemented.

DETAILED DESCRIPTION

Embodiments described herein are directed to immutable watermarking for authenticating and verifying artificial intelligence (AI)-generated output.

Adversarial Machine Learning (ML) is a rapidly emerging class of threats against ML models or training data during training and inferencing. Examples of such threats include:

Model extraction attack: An attacker attempts to extract or reverse engineer a trained model by inputting a large amount of data for inferencing and then analyze the inference results.

Model poisoning attack: An attacker purposely feeds incorrect input data during training to maliciously alter trained models. For example, an attacker may submit diagnostic image of a sick person and label it as not sick which would cause to model to be trained incorrectly for diagnosis operation.

Model inversion attack: An attacker attempts to recover training input data used to train a model by looking at statistics accompanying the inference results, such as confidence level. Confidence level of 100% may indicate parity with the input data used for training.

Evasion attack: An attacker modifies the input data to avoid detection of an attack.

Furthermore, the exponential growth of AI has introduced the problem of determining the trustworthiness and consequently the reliability of information and/or data generated from AI sources. There is no reliable solution to distinguish between the data (e.g. text or images) produced by state-of-the-art AI models (machine learning algorithm) versus data produced by humans. Inability to distinguish between AI-generated output and human-generated output is leading to security and ethical risks. For example, the lack of the traceability of data origin and the inability of “data” customers to perform controls and audit leads to the above-noted risks. Moreover, the use of unreliable information and/or data can weaken brand trust, which can violate regulations and trigger legal action against the consumer of the untrustworthy data.

One previous solution to address the above-noted data origin traceability problem is restriction of publishing AI-model generated output. However, this is not a practical solution as AI is being rapidly adopted, developed, and deployed across the compute continuum and complexity of the AI development supply chain.

Another previous solution to the above-noted data origin traceability problem is a watermarking approach for deep neural networks (DNN), where certain content is embedded in original training data as watermarks that are exhibited during inference when providing pre-specified predictions to the model. These prior watermarking approaches apply to protecting the DNN model using the input data (training data), and as such, can introduce distortion to the model. These distortions may, for example, change the meaning of the input data and modify the output of the model (e.g., lead to false negative or false positives).

Other previous solutions may utilize machine learning models or forensic systems to predict whether text was generated by a model or a human. These machine learning or forensics based solutions can also risk many false negative and/or false positive outcomes. In addition, implementation of these machine learning models or forensics systems is often not practical in industry applications as they are expensive and difficult to deploy and maintain.

Implementations of the disclosure address the above-noted data origin traceability problem by providing a system or process for immutable watermarking for authenticating and verifying AI-generated output utilizing a globally unique identifier (GUID). The GUID of implementations of the disclosure is used to authenticate and validate the output of content with respect to the identity of the author or owner of the outputted content (e.g., the ML model or human author). Implementations of the disclosure fuse the content data (e.g., ML-model generated data) with the GUID to enabled provenance identification and verification of the content data. Implementations of the disclosure utilize a watermarking approach based on three components to enable traceability of origin of content. The three components may include, but are not limited to, a sender, a verifier, and a shared AI registry (each of which are or are provided by trusted entities). Implementations of the disclosure provide protection of AI and ML models, and the output data generated from such models, in addition to supporting an end-to-end ML security pipeline by helping secure the authenticity and validity of output data. Implementations of the disclosure can address the ethical implications and protective measures that can be built as part of software to support efficient ML technologies.

FIG. 1 is an illustration of a system 100 to provide immutable watermarking for authenticating and verifying AI-generated output according to some embodiments. As illustrated in FIG. 1, system 100 includes a content generation platform 110, a shared AI registry 120, and a content consumer platform 130. Content generation platform 110, shared AI registry 120, and content consumer platform 130 may be communicably coupled via a wired or wireless network (not shown), such as a local or wide area network, or high speed interconnect. In some implementations, content generation platform 110, shared AI registry 120, and content consumer platform 130 may be directly communicably coupled via a wired or wireless connection.

In one embodiment, either of content generation platform 110 and/or content consumer platform 130 can include, a single processor desktop system, a multiprocessor workstation system, or a server system having a large number of processors (e.g., CPU 111, 131) or processor cores. In one embodiment, the content generation platform 110 and/or content consumer platform 130 can be a processing platform incorporated within a system-on-a-chip (SoC) integrated circuit for use in mobile, handheld, or embedded devices such as within Internet-of-things (IoT) devices with wired or wireless connectivity to a local or wide area network.

In one embodiment, either of content generation platform 110 and/or content consumer platform 130 couple with, or be integrated within: a server-based gaming platform; a game console, including a game and media console; a mobile gaming console, a handheld game console, or an online game console. In some embodiments the content generation platform 110 and/or content consumer platform 130 is part of a mobile phone, smart phone, tablet computing device or mobile Internet-connected device such as a laptop with low internal storage capacity. Content generation platform 110 and/or content consumer platform 130 can also include, couple with, or be integrated within: a wearable device, such as a smart watch wearable device; smart eyewear or clothing enhanced with augmented reality (AR) or virtual reality (VR) features to provide visual, audio or tactile outputs to supplement real world visual, audio or tactile experiences or otherwise provide text, audio, graphics, video, holographic images or video, or tactile feedback; other augmented reality (AR) device; or other virtual reality (VR) device. In some embodiments, the content generation platform 110 and/or content consumer platform 130 includes or is part of a television or set top box device. In one embodiment, content generation platform 110 and/or content consumer platform 130 can include, couple with, or be integrated within a self-driving vehicle such as a bus, tractor trailer, car, motor or electric power cycle, plane or glider (or any combination thereof). The self-driving vehicle may use content generation platform 110 and/or content consumer platform 130 to process the environment sensed around the vehicle.

In some embodiments, the content generation platform 110 and/or content consumer platform 130 include one or more processors, such as central processing unit (CPU) 111, 131, which each include one or more processor cores to process instructions which, when executed, perform operations for system or user software. In some embodiments, at least one of the one or more processor cores is configured to process a specific instruction set. In some embodiments, instruction set may facilitate Complex Instruction Set Computing (CISC), Reduced Instruction Set Computing (RISC), or computing via a Very Long Instruction Word (VLIW). One or more processor cores may process a different instruction set which may include instructions to facilitate the emulation of other instruction sets. Processor core may also include other processing devices, such as a Digital Signal Processor (DSP).

Content generation platform 110 includes one or more processors, such as a CPU 111, wherein the content generation platform 110 provides for processing of machine learning (ML) data. The ML processing may include at least some portion of the processing to be performed on a hardware accelerator 115, which is shown as including an ML model 116 for training or inference. An ML model may also be referred to herein as an AI model.

As used herein, “hardware accelerator” refers to a hardware device structured to provide for efficient processing. In particular, a hardware accelerator may be utilized to provide for offloading of certain processing tasks from a central processing unit (CPU) or other general processor, wherein the hardware accelerator may be intended to provide more efficient processing of the processing tasks than software run on the CPU or other processor. A hardware accelerator may include, but is not limited to, a graphics processing unit (GPU), neural processing unit, AI (Artificial Intelligence) processor, field programmable gate array (FPGA), or application-specific integrated circuit (ASIC).

In one implementation, content generation platform 110 provides for processing of ML data to generate content for consumption by content consumer platform 130. The generated content may be multi-modal content, including, but not limited to, one or more of plaintext, image(s), video(s), audio, and/or any other form of content. Content consumer platform 130 includes one or more processors, such as a CPU 131, where the content generation platform 110 provides for consumption of content generated by a content generation platform, such as content generated by processing of the ML data via ML model 116 at content generation platform 110. Consumption of content may include publishing content to a web page, adding the content into a monitoring system, or other processing of the content, for example. Content consumer platform 130 may include a content consumer component 134 (e.g., provided via CPU 131) that facilitates consumption of the content. For example, content consumer component 134 may include, but is not limited to, a web browser application, a mobile device application, a media player, a monitoring system, and so on.

A conventional system or process may implement algorithmic methods to detect and thwart adversarial attacks on the ML processing performed by the content generation platform 110, but this is insufficient to provide adequate protection from sophisticated adversarial attacks. In some embodiments, a system or process is to provide immutable watermarking for authenticating and verifying AI-generated output. In one implementation, the AI-generated output may refer to the content generated from processing the ML data via an inference stage of the ML model 116 at the content generation platform 110.

In one implementation, content generation platform 110 may provide a content generator 112 that generates multi-modal content, such as text, an image, a video, audio, or any other form of content. The content generator 112 may be implemented via hardware, software, and/or firmware of the content generation platform 110. The content generator 112 may utilize an ML model 116 to generate the content. For example, content generator 112 may utilize an inference stage of ML model 116 to generate text for publication to a document, such as a web page published to the Internet. In another example, content generator 112 may utilize an inference stage of ML model 116 to identify subject matter in a video for entry into a monitoring system, such as identification of an event recorded by a surveillance device. Other implementations of content generation for various use cases are envisioned in embodiments of the disclosure.

In implementations of the disclosure, the content generation platform utilizes a global unique identifier (GUID) to authenticate and validate the output of the ML model 116 by content generator 112. The GUID authenticates an identity of the ML model 116. Implementations of the disclosure include the GUID as part of a digital signature that is sent with the content to the content consumer platform 130. The content consumer platform 130 can utilize the GUID, as extracted from the received digital signature, in order to verify authenticity of the received content and, in particular, verify authenticity of the author (e.g., ML model 116, etc.) of the content. In some implementations, the digital signature includes a fusion of the generated content with model identification (including the GUID).

In some implementations, manual content generators (e.g., humans) are assigned a generic GUID, in order to perform the differentiation between a manual content generator (e.g., human) and an AI model. In some implementations, manual content generators are each assigned a unique GUID in order to differentiate individual provenance among manual content generators. The GUIDs are confidential and may be generated for purposes of assignment to an AI model or manual content generator.

Implementations of the disclosure implement a watermarking approach (i.e., watermarking pipeline) based on three components to facility traceability of data origin of content. Watermarking as discussed herein refers to the utilization of digital information hidden in a signal that can be used to verify the authenticity or integrity of the owner. The three components of implementations of the disclosure used in the watermarking approach include a sender, a verifier, and a shared AI registry. The three components may each be provided by a trusted entity and, as such, are considered individual trusted entities themselves. In one implementation, the sender may be one or more of the hash generator 113 and/or content deployer 114 of content generation platform 110. In one implementation, the verifier may be a verification component 132 of the content consumer platform 130. In one implementation, the shared AI registry may be the shared AI registry 120 of system 100.

With respect to the sender component, the hash generator 113 and/or content deployer 114 may be implemented in CPU 111 of content generation platform 110 as hardware, software, and/or firmware of the content generation platform 110. Once content is generated by content generator 112, the hash generator 113 may utilize the ML model's 116 GUID, a ML model ID, the content (e.g., plain text, image, video, etc.), and/or a timestamp for a digital signature. The content deployer 114 may then transmit the digital signature to the verifier component, along with the content (e.g., plain text, image, video, etc.), timestamp, and model ID. In one implementation, the digital signature and content, timestamp, and model ID may be sent over an insecure communication channel 140 to the verifier (e.g., verification component 132).

With respect to the verifier, the verification component 132 may be implemented in CPU 131 of content consumer platform 130 as hardware, software, and/or firmware of the content consumer platform 130. The verification component 132 verifies the digital signature of content to prove 1) if the content generation platform 110 and/or content generator 112 may have tampered the content and 2) if the content is from an ML model 116 with a unique GUID. In order to verify the content, the verification component 132 may utilize, in the case of content consumer component 134 being a web browser application, the previously downloaded public key of the website and the GUID, which is cached locally (e.g., at storage memory devices 118, 138) or sent from the sender to the verifier via a secure transmission channel 150.

The shared AI registry 120 maintains the record of the ML models' GUIDs indexed by model IDs 125. In one implementation, a model developer or model deployer could be responsible for generating the GUIDs and establishing the shared AI registry 120. The central location for the shared AI registry 120 may be provided by Internet Service Providers (ISPs) and/or Cloud Service Providers (CSPs) that could act as trusted entities. In particular, CSPs offer the building blocks for trusted environment and could serve a larger role in the pipeline. Implementations of the disclosure may be implemented for inference (i.e., ML models ready to be deployed), and the model developer can be assumed to be trustworthy during model training (i.e., the model developer does not introduce backdoors or unintended effects during training) and release.

In some implementations, the hash generator 113 and/or the verification component 132 can use a hash-based MAC (HMAC), which is a keyed hashing mechanism, as a basis for the digital signature. In the case of an HMAC, the GUID can act as key and at the same time uniquely identify the AI model that it is associated with. Other functions, such as PBKDF2, that are based on HMAC could also be used as well. As noted previously, the GUID can be sent from the sender (e.g., hash generator 113) to the verifier (e.g., verification component 132) through a secure transmission channel 150.

Implementations of the disclosure may be used in situations where the AI user/publisher (e.g., content generation platform 110) is present and can use the AI (e.g., ML model 116) to generate content that consumers perceive as trustworthy. For example, the use case of autonomous generation and publication of AI-generated text without utilizing a starting seed may implement aspects of the disclosure to enable differentiating between whether a human or AI authored the text, as well as determining which particular AI model authored the text. This may assist in determining output data lineage. Implementations of the disclosure may also be utilized in an Internet of Things (IoT) setting, where the data lineage of data generated by AI models (e.g., ML model 116) on edge devices can be identified without having to transmit details about the intrinsic implementation of the AI model, as described above. Further discussion of these particular use cases is provided with respect to FIGS. 2 and 3 below.

FIG. 2 is an illustration of a system 200 to provide immutable watermarking for authenticating and verifying AI-generated output in an example news consumption application, according to some embodiments. System 200 may include similar components as system 100 described with respect to FIG. 1 and their corresponding description above is similarly applied with respect to system 200.

System 200 implements a watermarking approach (i.e., watermarking pipeline) to facilitate traceability of data origin with respect to autonomous generation and publication of AI-generated text. For example, system 200 may reflect a news consumption use case. System 200 includes a model developer system 202, a model deployer system 210, an AI/model user system 220, a manual content generator 230, an adversary system 240, a content consumer system 250, and a shared AI registry 260.

The model developer system 202 may include an ML model generator 204 and a ML model updater 206. The ML model generator 204 may train and generate an ML model (e.g., ML model 116 of FIG. 1) for deployment in an ecosystem. The ML model updater 206 may be responsible for updating training of the generated ML model. In implementations of the disclosure, the model developer system 202 is assumed to be trustworthy during model training (i.e., the model developer does not introduce backdoors or unintended effects during training) and model release.

The ML model generated and/or updated by model developer system 202 may be provided to model deployer system 210. Model deployer system 210 includes an ML model deployer component 215 that can host the ML model for inference purposes. The model deployer system 210 may host the ML model using machine learning-as-a-service. In some implementation, the model deployer system may not collaborate with the model developer system 202 to host the ML model.

The ML model deployer component 215 can make the ML model 226 available to an AI/model user system 220 for inference. The AI/model user system 220 may implement content generator 222 to provide the starting text for the trained model 226 to make inferences, and optionally takes the output of the ML model 226 and publishes it via publication component 224. The publication component 224 may publish the output to a web page, for example.

The publication component may communicate with content consumer system 250 to cause the output of the ML model 226 to be published. For example, content consumer system 250 may be a computing device hosting a content consumer application 254, such as a web browser or other content application, that causes publication of content for consumption by an end user.

In some implementations, a manual content generator 230 may also publish content for consumption at content consumer system 250. The manual content generator 230 may provide content directly generated by a manual user, such as a human user, as opposed to content generated by an AI model.

In some implementations, an adversary system 240 may also publish content using an AI model, but in a manner that tricks a content consumer into believing the content is from a reputable human source or a legitimate AI model.

Implementations of the disclosure provide a watermarking approach to verify the authenticity or integrity of the owner of content published and consumed at content consumer system 250. The watermarking approach prevents the publishing and/or consumption of unverified content at the content consumer system 250. As such, content generated by the adversary system 240 that is not verifiable at the content consumer system 250 is not published and/or consumed at the content consumer system 250.

In implementations of the disclosure, a GUID 270 is used to authenticate and validate content provided for consumption at content consumer system 250. The content consumer system 250 may include a verification component 252 that verifies whether content received at the content consumer system 250 is associated with an authenticated GUID 270. If so, the content is considered to be verified content 256 that can be provided for content consumer application 254 for user consumption. In one implementation, the verification component 252 is the same as verification component 132 described with respect to FIG. 1. In some implementations, if the verification component 252 is not able to locate and/or verify a GUID associated with received content, then the verification component 252 may refuse the content for purposes of consumption at content consumer application 254.

When content is generated for publication at the AI/model user system 220, a hash generator 228 can be used to generate a digital signature for the generated content, where the digital signature includes at least the GUID 270. In one implementation, the hash generator 228 is the same as hash generator 113 described with respect to FIG. 1. The hash generator 228 may be a trusted component that is provided for hosting by the AI/model user system 220 from a trusted entity. Similarly, the verification component 252 may also be a trusted component that is provided for hosting by the content consumer system 250 from a trusted entity.

The hash generator 228 may utilize a GUID 270 corresponding to the ML model when generating the digital signature. The GUID 270 may be obtained by the hash generator 228 from the shared AI registry 260. In one implementation, the shared AI registry 260 is the same as shared AI registry 120 described with respect to FIG. 1 and maintains a data store 265 of ML models' GUIDs indexed by model IDs, for example. In one implementation, the model developer system 202 or model deployer system 210 could be responsible for generating the GUIDs 270 for various ML models (Such as ML model 226) and/or manual content generators (such as manual content generator 230) and establishing the shared AI registry 260. As previously discussed, the shared AI registry 260 may be provided in a central location by ISPs and/or CSPs that act as trusted entities. As noted previously, the GUID 270 can be obtained at the hash generator 228 from the shared AI registry 260. In some implementations, the hash generator 228 may send the GUID 270 to the verification component 252 through a secure transmission channel. In some implementation, the verification component 252 may obtain the GUID 270 from the shared AI registry 260.

In one implementation, the digital signature generated by hash generator 228 may be a hash of one or more the generated content (e.g., plaintext), the GUID 270, a ML model ID, and/or a timestamp. In some implementations, the hash generator 228 can use a HMAC to generate the digital signature. Once the digital signature is generated by hash generator 228, the publication component 224 may then transmit the digital signature, along with the content (e.g., plain text), timestamp, and model ID to the content consumer system 250. In one implementation, the digital signature and content, timestamp, and model ID may be sent over an insecure communication channel to the content consumer system 250.

As previously discussed, the verification component 252 of content consumer system 250 verifies the digital signature of content prior to passing it to content consumer application 254 as verified content 256. Verification of the content by verification component 252 is performed to determine 1) if provider of the content (e.g., AI/model user system 220, manual content generator 230, adversary system 240) may have tampered the content and 2) if the content is from an ML model (e.g., ML model 226) or other author (e.g., manual content generator 230) with a unique GUID 270. In order to verify the content, the verification component 252 may utilize a previously downloaded public key of a website and the GUID 270. As previously noted, the GUID 270 may be cached locally at the content consumer system 250 (e.g., subsequent to being provided from the hash generator 228) or obtained from the shared AI registry 260. As shown in FIG. 2, if adversary system 240 provides content to content consumer system 250 without a verifiable GUID, the verification component 252 determines that the received content is not associated with a valid GUID and can refuse the content for purposes of consumption at the content consumer application 254. In some implementations, the verification component 252 might still allow the content for consumption at content consumer application 254 but may provide a notification and/or warning with the content indicating that the content is not associated with a verified source.

FIG. 3 is an illustration of a system 300 to provide immutable watermarking for authenticating and verifying AI-generated output in an example digital monitoring application, according to some embodiments. System 300 may include similar components as system 100 described with respect to FIG. 1 and/or system 200 described with respect to FIG. 2. As such, the corresponding descriptions from FIGS. 1 and 2 above is similarly applied with respect to system 300.

System 300 implements a watermarking approach (i.e., watermarking pipeline) to facilitate traceability of origin of content with respect to digital monitoring systems. For example, system 300 may reflect a digital surveillance use case. System 300 includes a model developer system 302, a model deployer system 310, an edge device 320, a manual surveillance system 330, an adversary system 340, a monitoring system 350, and a shared AI registry 360.

The model developer system 302 may include an ML model generator 304 and a ML model updater 306. The ML model generator 304 may train and generate an ML model (e.g., ML model 116 of FIG. 1) for deployment in an ecosystem, such as an ML model that can identify certain events typical to a digital surveillance ecosystem. The ML model updater 306 may be responsible for updating training of the generated ML model. In implementations of the disclosure, the model developer system 302 is assumed to be trustworthy during model training (i.e., the model developer does not introduce backdoors or unintended effects during training) and model release.

The ML model generated and/or updated by model developer system 302 may be provided to model deployer system 310. Model deployer system 310 includes an ML model deployer component 315 that can host the ML model for inference purposes. The model deployer system 310 may host the ML model using machine learning-as-a-service. In some implementation, the model deployer system may not collaborate with the model developer system 302 to host the ML model.

The ML model deployer component 315 can make the ML model 326 available to an edge device 320 for inference. The edge device 320 may include a data capture component 322 to capture images, audio, and/or video content as part of monitoring an environment. The inference generator 323 may analyze the captured images, audio, and/or video from the data capture component 322 and apply the ML model 326 to such content to make inferences on the captured content. The inference generator 323 may optionally takes the output of the ML model 326 and publishes it via reporting component 324. The reporting component 324 may report the output of the inferences of ML model 326 to a monitoring system for logging, for example.

The reporting component 324 may communicate with monitoring system 350 to cause the output of the ML model 326 to be recorded. For example, monitoring system 250 may be a computing device hosting a monitoring consumption application 354 that causes logging of monitored events for analysis and review (e.g., consumption) by an end user.

In some implementations, a manual surveillance system 330 may also generate content for consumption at monitoring system 350. The manual surveillance system 330 may provide content directly generated by a manual user, such as a human user, as opposed to content generated by an AI model (such as ML model 326).

In some implementations, an adversary system 340 may also generate content using an AI model or otherwise, but in a manner that tricks a content consumer into believing the content is from a reputable human source or a legitimate AI model.

Implementations of the disclosure provide a watermarking approach to verify the authenticity or integrity of the owner of content reported and consumed at monitoring system 350. The watermarking approach prevents the reporting and/or consumption of unverified content at the monitoring system 350. As such, content generated by the adversary system 340 that is not verifiable at the monitoring system 350 is not reported, logged, and/or consumed at the monitoring system 250.

In implementations of the disclosure, a GUID 370 is used to authenticate and validate content provided for consumption at monitoring system 350. The monitoring system 350 may include a verification component 352 that verifies whether content received at the monitoring system 350 is associated with an authenticated GUID 270. If so, the content is considered to be verified content 356 that can be provided for monitoring consumption application 354 for user consumption. In one implementation, the verification component 352 is the same as verification component 132 described with respect to FIG. 1. In some implementations, if the verification component 352 is not able to locate and/or verify a GUID associated with received content, then the verification component 352 may refuse the content for purposes of consumption at monitoring consumption application 354.

When content is generated for reporting at the edge device 320, a hash generator 328 can be used to generate a digital signature for the generated content, where the digital signature includes at least the GUID 370. In one implementation, the hash generator 328 is the same as hash generator 113 described with respect to FIG. 1. The hash generator 328 may be a trusted component that is provided for hosting by the edge device 320 from a trusted entity. Similarly, the verification component 352 may also be a trusted component that is provided for hosting by the monitoring system 350 from a trusted entity.

The hash generator 328 may utilize a GUID 370 corresponding to the ML model 326 when generating the digital signature. The GUID 370 may be obtained by the hash generator 328 from the shared AI registry 360. In one implementation, the shared AI registry 360 is the same as shared AI registry 120 described with respect to FIG. 1 and maintains a data store 365 of ML models' GUIDs indexed by model IDs, for example. In one implementation, the model developer system 302 or model deployer system 310 could be responsible for generating the GUIDs 370 for various ML models (such as ML model 326) and/or manual content generators (such as manual surveillance system 330) and establishing the shared AI registry 360. As previously discussed, the shared AI registry 360 may be provided in a central location by ISPs and/or CSPs that act as trusted entities. As noted previously, the GUID 370 can be obtained at the hash generator 328 from the shared AI registry 360. In some implementations, the hash generator 328 may send the GUID 370 to the verification component 352 through a secure transmission channel. In some implementation, the verification component 352 may obtain the GUID 370 from the shared AI registry 360.

In one implementation, the digital signature generated by hash generator 328 may be a hash of one or more the generated content (e.g., image, video, audio, etc.), the GUID 370, a ML model ID, and/or a timestamp. In some implementations, the hash generator 328 can use a HMAC to generate the digital signature. Once the digital signature is generated by hash generator 328, the reporting component 324 may then transmit the digital signature, along with the content (e.g., image, video, etc.), timestamp, and model ID to the monitoring system 350. In one implementation, the digital signature and content, timestamp, and model ID may be sent over an insecure communication channel to the monitoring system 350.

As previously discussed, the verification component 352 of monitoring system 350 verifies the digital signature of content prior to passing it to monitoring consumption application 354 as verified content 356. Verification of the content by verification component 352 is performed to determine 1) if provider of the content (e.g., edge device 320, manual surveillance system 330, adversary system 340) may have tampered the content and 2) if the content is from an ML model (e.g., ML model 326) or other author (e.g., manual surveillance system 330) with a unique GUID 370. In order to verify the content, the verification component 352 may utilize the GUID 370. As previously noted, the GUID 370 may be cached locally at the monitoring system 350 (e.g., subsequent to being provided from the hash generator 328) or obtained from the shared AI registry 360. As shown in FIG. 3, if adversary system 340 provides content to monitoring system 350 without a verifiable GUID, the verification component 352 determines that the received content is not associated with a valid GUID and can refuse the content for purposes of consumption at the monitoring consumption application 354. In some implementations, the verification component 352 might still allow the content for consumption at monitoring consumption application 354 but may provide a notification and/or warning with the content indicating that the content is not associated with a verified source.

FIG. 4 illustrates an example flow 400 for immutable watermarking for authenticating and verifying AI-generated output by a content generation platform, in accordance with certain embodiments. The various operations of the flow may be performed by any suitable circuitry, such as a controller of a host computing device, a controller of a memory module, or other components of a computing device. The example flow 400 may be representative of some or all the operations that may be executed by or implemented on one or more components of system 100 of FIG. 1, such as a processor (e.g., CPU 111). The embodiments are not limited in this context.

At block 410, the processor may generate content using an inference stage of an ML model. At block 420, the processor may identify a global unique identifier (GUID) for the ML model.

Subsequently, at block 430, the processing may generate a digital signature for the content, the digital signature based on at least the GUID of the ML model and the content generated by the ML model. Lastly, at block 440, the processor may transmit the content and the digital signature to a content consumer platform.

Some of the operations illustrated in FIG. 4 may be repeated, combined, modified or deleted where appropriate, and additional steps may also be added to the flow in various embodiments. Additionally, steps may be performed in any suitable order without departing from the scope of particular embodiments.

FIG. 5 illustrates an example flow 500 for immutable watermarking for authenticating and verifying AI-generated output by a content consumption platform, in accordance with certain embodiments. The flow 500 may be representative of some or all the operations that may be executed by or implemented on one or more components of system 100 of FIG. 1, such as a processor (e.g., CPU 131). The embodiments are not limited in this context.

In the illustrated embodiment shown in FIG. 5, the flow 500 may begin at block 510. At block 510, the processor may receive, by a processor of a content consumer platform, content generated by a machine learning (ML) model and a digital signature corresponding to the content. At block 520, the processor may process the digital signature to extract, from the digital signature, a global unique identifier (GUID) of the ML model that generated the content.

Subsequently, at block 530, the processor may verify the extracted GUID against data obtained from a shared registry, the data obtained from the shared registry comprising identifying information of the ML model including the GUID. At decision block 540, the processor determine whether the extracted GUID is successfully verified.

If the extracted GUID is successfully verified at decision block 540, the flow 500 proceeds to block 550 where the processor may provide the content for consumption at the content consumer platform and indicating that the content is generated by the ML model having verified authenticity. On the other hand, if the extracted GUID is not successfully verified at decision block 540, the flow 500 proceeds to block 560 where the processor may refuse the content for consumption at the content consumer platform and indicate that the ML model generating the content is not verified for authenticity.

Some of the operations illustrated in FIG. 5 may be repeated, combined, modified or deleted where appropriate, and additional steps may also be added to the flow in various embodiments. Additionally, steps may be performed in any suitable order without departing from the scope of particular embodiments.

 17. The method of claim 16, wherein the GUID comprises a unique identifier of the ML model that corresponds to a model identifier (ID) of the ML model.
 18. The method of claim 16, wherein the shared registry comprises a trusted entity that is separate from the content consumer platform.
 19. The method of claim 16, wherein the digital signature comprises a hash-based message authentication code (HMAC) of the content and the GUID.
 20. The method of claim 16, wherein the digital signature comprises a hash-based message authentication code (HMAC) of the content, the GUID, a model identifier (ID) of the ML model, and a timestamp corresponding to generation of the content.
